1 Claim.

This invention appertains to new and usefu improvements in tractionincreasing appliances for vehicle wheels. The invention moreparticularly relates to a traction increasing cleat for dual wheelassemblies.

The principal object of the present invention is to provide a tractionincreasing device for dual wheel assemblies constructed in such a manneras to permit clamping of the cleated piece with the cleat properbridging the tread portions of the complementary wheels.

Another important object of the invention is to provide a device of thecharacter stated which can be easily applied and removed.

These and other important objects and advantages of the invention willbecome apparent to the reader of the following specification.

In the drawings:

Figure 1 is a fragmentary tread elevational view of a dual wheelassembly showing a pair of the traction increasing device applied.

Figure 2 is a fragmentary side elevational view showing one of thedevices applied.

Figure 3 is a fragmentary enlarged sectional view taken substantially onthe line 3-3 of Figure 2.

Figure 4 is an enlarged perspective view of the traction increasingdevice.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 generally refers to a dual wheel assemblyconsisting of rims 6, 6, sheet steel disks or webs I, I connecting therims 6 with corresponding hubs 8, and tires 9, 9 mounted on the rims IS,6. As is common, the wheel disks 1, 1 are formed with openings I0adjacent the outer edge portion thereof and it is in conjunction withthese openings that the present invention, which is generally referredto by numeral II is employed.

The present invention specifically consists of an elongated treadtraversing plate I2 havin obliquely disposed end portions I3 adapted tooverlap outermost portions of the tires 9, 9, as in the manner shown inFigure 3. This plate I2 is narrow and is provided With a substantiallyinverted U-shaped riser I4 at the intermediate portion thereof,apertured to receive the corresponding threaded end of a tie rod I5.Nuts I6 and H are provided on this threaded end portion of the rod I5,at the outside and inside of the riser I I, these nuts being fed on thethreaded portion to bind against the inside and outside of the riser I4to hold the rod I5 in definite position projecting outwardly atsubstantial right angles to the plate I2.

Numeral I8 denotes a bridge plate having laterally turned end portionsI9, I9 which overlap edge portions of the disks I at the openings I0therein. The intermediate portion of this bridge member I8 has anopening for receiving the remaining and threaded end portion of the rodI5 and a nut 20 is provided on this end portion of the rod I5. When thetread plate I2 is properly disposed across the tread portions of thetires 9, 9, and the rod I5 disposed through the opening in the bridgeplate I8, the nut 20 can be applied and fed down to a position tightlyagainst the bridge plate I8, so as to firmly maintain the tread plate I2against the tread portions of the tires 9, 9. As is clearly shown inFigures 2 and 4, a cleat 2| is provided on the round engaging side ofthe plate I2 and extends diagonally across the plate, the purpose inhaving the cleat disposed diagonally being to permit the same to cleanitself of mud and other accumulations.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the claimed as new is:

A traction increasing device for dual disk wheel assemblies wherein theadjacent wheels are slightly spaced apart and the webs thereof areprovided with opposed edge openings; a tread plate disposed transverselyacross the tires of a dual wheel assembly and having angular straightend portions for fitting against the outermost side portions of thetires of the dual wheel assembly, an open tapered riser at theintermediate portion of the bridge member adapted to be wedged betweenthe tires and having an opening in the outer portion thereof, anelongated rod for disposition between the wheels of an assembly andhaving one end disposed through the opening in the riser, and providedwith securing means thereon for securing the rod to the riser, and aclamp structure at the remaining end of the rod comprising a flat baradapted to be inserted at its ends into said openings to bear againstthe edges thereof, said ends being inclined to prevent the same fromcreeping off said edges, said tread plate having a traction increasingcleat thereon.
